Introductory meeting (mandatory):
The introductory meeting will take place on Thursday, July 27, 2017, 2:15 p.m., in E1.7, Room 4.10.
In this meeting, we will assign the topics to the participants. Attendance is mandatory for all participants. Do not forget to register first (see below).

Regular meetings during the winter term 2017/2018:
Tuesday, 4:15 p.m., in Building E1.7, Room 4.10


Contents: Digital network traffic has been rising rapidly during the last decades and continues to increase. A large portion of this traffic is generated by video content making the efficient compression of videos a vital task.
Hybrid Video Coding (HVC) is a key concept in the field of video compression which relies on prediction and subsequent correction. It is deployed in practically all established coding standards such as HEVC and VP9.
In this seminar, we will discuss the main ideas behind HVC and their realisation in encoders and decoders. To this end, we will cover basic to state-of-the-art methods for the different modules and tasks within HVC.

Prerequisites: The seminar is for advanced bachelor or master students in Visual Computing, Mathematics, or Computer Science. Basic mathematical knowledge (e.g. Mathematik für Informatiker I-III) and some knowledge in image processing and computer vision is required.

Language: All papers are written in English, and English is the language of presentation.


The registration period is over.


Regular attendance: You must attend all seminar meetings, except for provable important reasons (medical certificate).

Talk: Talk duration is 30 min, plus 15 min for discussion . Please do not deviate from this time schedule.
You may give a presentation using a data projector, overhead projector or blackboard, or mix these media appropriately. Your presentation must be delivered in English. Your slides and your write-up, too, have to be in English.

Write-up: The write-up has to be handed in three weeks after the lecture period ends. The write-up should summarise your talk and has to consist of 5 pages per speaker. Electronic submission is preferred. File format for electronic submissions is PDF – text processor files (like .doc) are not acceptable. Do not forget to hand in your writeup: Participants who do not submit a writeup cannot obtain the certificate for the seminar.

Plagiarism: Adhere to the standards of scientific referencing and avoid plagiarism: Quotations and copied material (such as images) must be clearly marked as such, and a bibliography is required. Otherwise the seminar counts as failed.

Mandatory consultation: Talk preparation has to be presented to your seminar supervisor no later than one week before the talk is given. It is your responsibility to approach me timely and make your appointment.

No-shows: No-shows are unfair to your fellow students: Some talks are based on previous talks, and your seminar place might have prevented the participation of another student. Thus, in case you do not appear to your scheduled talk (except for reasons beyond your control), we reserve the right to exclude you from future seminars of our group.

Participation in discussions: The discussions after the presentations are a vital part of this seminar. This means that the audience (i.e. all paricipants) poses questions and tries to find positive and negative aspects of the proposed idea. This participation is part of your final grade.

Being in time: To avoid disturbing or interrupting the speaker, all participants have to be in the seminar room in time. Participants that turn out to be regularly late must expect a negative influence on their grade.


Here are the slides from the introductory meeting. They contain important information for preparing a good talk.
